Method and device for service adaptation

Abstract

The embodiment of the invention discloses a device for service adaptation, which comprises a service access unit and an package form E-GEM adaptation unit of an enhanced type gigabit passive optical network, wherein the service access unit is used for acquiring uplink direction service data on a service adaptation layer; the service data comprises any one of or the combination of more than one of package form GEM frame of payload data, time division multiplexing (TDM) service data and internet protocol (IP) data of the gigabit passive optical network; and the package form E-GEM adaptation unit of the enhanced type gigabit passive optical network is used for packaging the uplink direction service data into an uplink E-GEM frame which at least comprises a destination identifier and a payload length indicator (PLI) of a service. The embodiment of the invention also provides a method for the service adaptation. By using the device, provided by the embodiment of the invention, for the service adaptation, the unified adaptation of a plurality of services can be realized simply and conveniently to provide convenience for a network upper layer to manage and transmit various service data in a unified mode.

Description

A service adaptation method and service adaptation device technical field The present invention relates to the field of communication technologies, and in particular to a service adaptation method and a service adaptation device. Background technique With the development of network communication technology, existing networks can carry various services, such as voice, video, online games, and web browsing. Currently, there are many technologies for carrying multiple services in the metropolitan area network, including technologies based on Synchronous Digital Hierarchy (SDH, Synchronous Digital Hierarchy), Ethernet technologies, and the like. Among them, when the equipment in the SDH system is used to bear the Ethernet business, because the transmission rate of the Ethernet does not match the net load of the SDH system (wherein, the transmission rate of the Ethernet includes: 10Mbit / s, 100Mbit / s and 1000Mbit / s s, etc.; the net load of the SDH system includes 2Mbit / s, 34Mb...

AI Technical Summary

Problems solved by technology

However, because the Ethernet system does not support transparent transmission of clock performance, the quality of clock transmission is not guaranteed, and it is difficult to support clock-sensitive service access

During the research and practice of the existing technology, the inventors of the present invention found that the existing technology for realizing multiple service bearers has disadvantages such as complex technology, no support for dynamic bandwidth adjustment function, and low QoS performance.

And because in recent years, many large telecom operators have chosen to use Gigabit-Passive Optical Network (GPON, Gigabit-Passive Optical Network) as the solution for future large broadband optical fiber access, and put forward higher requirements for metropolitan area network equipment. Requirements to support the development of future fiber access (FTTx, FiberToTheBuilding / Cabinet / Curb / Home, fiber to the building, roadside cabinet, home and other forms of access), which cannot be realized in the existing technology
